BALL-BEARING.

No. 799,008. Specification of Letters Patent. Patented Sept. 5, 1905.

To H]? 117mm if Nb/[j] concern:

Be it known that I, Ema KLAHX, a citizen of the United States, and a resident of \Ycst Hoboken. in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Ball-Bearings, of which the following is a specification.

My invention relates especially to improvements in ball-retaining devices for ball-bearings; and it has for its object the provision of a simple and effective device by which the balls in a bearing may be kept separate and the friction due to the rubbing of the balls upon one another prevented.

The above object is obtained by the constructions shown in the accompanying drawings, in which- Figure l is a view of a blank for making a ball-retaining device. Fig. 2 is a plan view of a ball-retainer formed from a blank of the kind shown in Fig. 1 and supplied with a full complement of balls. Fig. 3 is a view in section uponthe line33of Fig. 2. Fig. is a plan view of a somewhat difi'erent form of ballretaining device supplied with balls. Fig. 5 is a plan view of the blank from which the ballretaining device shown in Fig. 4: is formed. Fig. 6 is a sectional view on the line 6 6 of Fig. 4:. Fig. T is a view of a hub with one end in section. showing the ball-retaining device illustrated in Figs. 4, 5, and 6 as applied to a ball-bearing. I

Similar characters of reference ind icate corresponding parts in the several figures.

Figs. 1, 2, and 3 are copied from my prior patent, No. 611,689, granted October -I, 1898.

Referring to the drawings, A designates a ring-shaped base of sheet metal, which is shown in the drawings as concave and is provided at its outer margin with projecting flaps (1, which are radially arranged and are spaced atsubstantiallyequaldistances apart,as shown. The flaps a, which are adapted to be bent upwardly, so as to stand substantially at right angles to the plane of the base and form standards, are provided with extensions 7), the opposite sides of which are scalloped or inwardly curved. The extensions are designed to be bent so as to overhang the base and lie substantially parallel thereto when the flaps are bent upward to form standards.

In Figs. 4:, 5, and 6 I have illustrated aballretaining device having a ring-shaped concave base A, of sheet metal, from the inner margin of which extend flaps a, which are spaced at equal distances and extend toward the center of the ring-shaped base. The flaps u are designed to be bent imwardly, as shown in Fig. 6,130 form standards, and they are provided with flaring or laterally-enlarging extensions 6. These tiaring or latorally-cnlarging extensions 7) are designed to be bent to overhang the base, as shown in Fig. 6, and to lie substantially parallel with the plane of the base.

In both forms of ball-retaining device above described the standards and extensions thereof cooperate with the base to create spaces into which balls B may be sprung without difliculty, the standards and extensions yielding sufficiently to permit the balls to be sprung or snapped into the spaces. \Vhen the balls are in position in the spaces presented by a retainer of either form, they will be effectively held against displacement, but they will be permitted to rotate freely, and each ball will be kept out of contact with others. The ballretaining devices of either type are applied to ball-bearings, as shown in Fig. 7. One of the ball-retaining devices with its complement of balls is placed in one of the ball-cups C of the hub, and the corresponding cone 1) is then screwed upon the end of the shaft E until proper adjustment is obtained. The cones of the bearings can rotate within the cups or the cups can turn on the cones, as the case may be, without interference with or from the lull-retaining devices.

In Fig. 7 only one end of the hub is shown as provided with a ball-retaining device. If a ball-retaining device be used in the other end of the hub, it will be placed in precisely the same position, and additional description seems unnecessary.

It is a well-known fact that in the common ball-bearing a considerable amount of friction is frequently due to the rubbing of the balls upon one another. Such friction cannot occur in ball-bearings equipped with the improved ball-retaining devices.

It will be noted that the ball-retaining devices shown and described are characterized by concave ring-shaped bases. form of the bases adds materially to their rigidity, as will be obvious, and prevents the distortion of the base except when subjected to violent strains.

Having thus described my invention, I claim as new and desire to sccu re by Letters Patent-- 1. A ball-retaining device for ball-bearings, consisting of a ring-shaped portion or base having a series of spaced standards rising at one margin only of the base and having their The concave free ends extended to overhang the base, said free ends being so formed that suitable spaces are presented for receiving and confining balls Without preventing free rotation of the balls.

2. A ball-retaining device for ball-bearings, consisting of a ring-shaped portion or base and a series of spaced standards rising at one margin only of the base, the base being concave and the standards having their free ends extended to overhang the base, the free ends of the standards being so formed that suitable spaces are presented for receiving and confining balls without preventing free rotation of the balls.

3. A ball-retaining device for ball-bearings, consisting of a ring-shaped portionor base and a series of spaced standards rising at one margin only of the base, the base being relatively stiif and the standards relatively elastic and having their free ends extended to.
